Installshield Tuner Not working

I am trying to create a .MST file for 6.0.1CF client so that it will install silently on my client machines in multi-user mode. I had a copy of installshield Admin Studio so I use the tuner come with it to open Notes’ msi file. (the only purpose of ITW file is licensing! I did the same on some other apps and it works everytime)

I modified features and properties following the help file, but after installation I was frustrated to find that it’s still in single user mode!

Anyone who know how to get this SPECIAL PIECE OF SOFTWARE installed on my will?
